I have an 8" Palmgren rotary table. The table is marked with 180

turn of the crank turns the table 9 divisions, or 18 degrees, making one
division on the crank .18 degrees. Nothing appears to be direct reading.
Is the design screwy, or do I not know the proper technique?

That sounds like a non-standard rotary table. If one turn turns the
table 18 degrees, than the rotary table has a 20:1 gear ratio. Not
what I would expect. 40:1 is what I would expect.

The MSC catalog has Palmgren rotary tables listed, but they are all
40:1 gear ratios. Would you mind checking one more time what the gear
ratio is? I just find it hard to believe that your rotary table has a
20:1 gear ratio.
